JAMES G. TOBIAS, OF BUCYBUS,OHIO.

GRAIN -E LE VATOR.

Specification of Letters Patent.

Patented Nov. 17', 1908. Y

Application filed. February 28, 1907. Serial No. 359,839.

To all whom it may concern:

Be it known that I, JAMES C. Tonnes, a citizen of the United States, residing at Bucyrus, in the county of Crawford and State of Ohio, have invented certain new and useful Improvements in Grain-Elevators, of which the following is a specication.

My invention relates to grain elevators and particularly to improvements upon the construction set forth in my Patent No. 837,518 of December 4L, 1906.

The object of the present invention is to combine with the Ventilating and conveying features of the elevator of that patent, means whereby the outer doors covering the ventilating screens may be dispensed with and effective protection of the screens and openings against the entrance of water, aorded.

To this end my invention is embodied in preferable form in the arrangement hereinafter described and illustrated in the accompanying drawings.

In these drawings, Figure 1 is a side view in elevation partly in section of my improved elevator; Fig. 2 is an end view in perspective, with end wall of building partly broken away; Fig. 8 is a horizontal section; Fig. t is an enlarged detail vertical section of hood and screen; Fig. 5 is an enlarged front elevation detail of the protecting weather boarding. constituting the hood and showing the same partly broken away to disclose the screen; Fig. 6 is an end view in elevation showing fiat instead of inclined floors and Fig. 7 is a sectional detail showing a solid door for the partition screen.

Referring to the drawings, the elevator comprises preferably a main central portion 1 provided with a top 2 smaller than the main portion and both having slanting roofs 3.

At approximately the center of the main portion 1, an endless vertical conveyer 4.-, is provided for elevating the grain from a boot 5, preferably situated below the floor of the elevator, to the upper portion of said main chamber from whence the grain is adapted to be distributed to suitable bins on either side of said main central part.

Communicating with and extending from the main central portion on either side thereof are wings 7 and 8 lower in height than the central part of the building thus providing an elevator building whose greatest dimension shall be disposed horizontally so as to thereby obtain economy of space and a of said wings is mounted a horizontally eX- tending conveyer 19 independent of the conveyer 12. These conveyers 19 are adapted to engage and carry along the grain which is fed to the belt. The conveyers 19 engage pulleys 2O:i and are designed to deliver grain to the boot 5 and 21 designates the trough through which the conveyers are adapted to travel. These troughs are each provided with a suitable chute 28, at the end designed to deliver grain to the boot 5, as the grain is fed from the several bins to the endless conveyers 19, from which boot it may be loaded upon a car, wagon or other receptacle. To facilitate the unloading of the grain to the boot, the central portion of the building in which said boot is formed has its Hoor raised above the floors of the adjacent wings.

A series of storage bins 24, 25, 26, and 27 of any desired number are provided in each side of the wings 7 and 8 according to the length of the wings which wings are separated longitudinally by a central longitudinal passage having partition walls and by cross partitions extending vertically between the bins.

Pipes 22 extend downward from the head of the endless vertical conveyer 4t and deliver the grain from said endless conveyer head to the horizontal conveyers 12 in the wings.

Formed in the walls of the wings at each bin between vertical posts 80b is a Ventilating frame 28 consisting of a wire screen, crossed wires, perforated sheets, iron rods, wooden slats, or any similar construction. This frame extends from the Hoor upwardly about of the height of the building and provides a separate efficient means of ventilation for the grain in each bin. Over the outside of this frame the outer wall is offset' from the upper part thereof to form a protecting hood 8O secured firmly to the vertical posts 30h extending from the water table downwardly to the bottom of the sill. This outwardly projected weather boarding or hood extending from the water table 30C to the bottom of the sill is separated from the upper part of the wall and the Ventilating frame 2S by a distance of about four inches thus affording a space at the bottomv extending vertically upward between the Ventilating frame and the weather boarding or hood that will permit the free circulation of air at all times between such parts so as to afford athorough Ventilation of the bins, while at the same time the hood thus formed provides an effective protection against the entrance of water. Each bin is also provided with an imperforate inside door 29 hinged at the top and adapted to cover the Ventilating frame 28 when swung down into closed position whereby upon the closing of such doors the elevator will be adapted to the storing of small grain such as wheat and shelled corn. The hooded weather boarding extends the entire length of each wing.

At the center of each of the wings and at the rear of the several bins is a passage way 30, access to which is had by means of the doors at the ends of the wings and form the central portion 1 of the ele- Vater building. At the top of passage way 30a a series of wires, iron rods, perforated sheets, or wooden slats 24a are provided to allow air to pass from the passage way upward to the cupolas 9 and 10 and at the same time provide a suitable support for the ear-corn. Doors or covers 30d hinged to the central partition, are provided above the central passage way 30a and adapted to be closed down over the screen supports 24a when the bins are used for the storage of small grain.

The bottom 31 of the bins are preferably inclined downward as shown in Fig. 6 for the purpose of facilitating the feeding of the grain from the bins to the conveyers 19 when it is desired to transfer the grain out of the bins, and 32 designates slides for closing the openings in the lower portions of said bins. In Fig. 2 these sliding closures are of perforated or screen material, while in Fig. 7 a modified construction consisting of solid doors for the purpose of adapting the partition to small grain is provided.

The bottom 31 is provided with an open work Ventilating support or screen 36, extending the length of the wing and similar to the perforated screens 28, and this screen like the parts 29, is adapted to close the spaces in each bin for the purpose of tightly closing the'bins and forming a support for small gram.

In Fig. 2 the floors 31 are shown as flat.

rThe end of each wing is provided with an outside door for the purpose of affording ventilation from end to end thereof.

The operation is as follows: Power is transmitted direct from a gas or steam engine (not shown) by belt to pulley 32D on shaft 33. Lower longitudinal conveyers 19 are driven by right-hand quarter-twist belts 34e. Upper longitudinal conveyers 12 are driven by left-hand quarter-twist belts 35, which connect with pulleys on shaft 33. Vertical elevator 4 is driven direct by open belt 33a. By this method all counter-shafts are dispensed with and all belting is done from one central line shaft suspended by drop hangers from the upper fioor joints. When the bins are to be filled, grain is conveyed from a wagon or other receptacle to the boot 5 through either main side entrance and then elevated by the main elevator a to the pipes 22 and thence down said pipes onto the upper couveyer belts 1Q and by them carried along the troughs 16 and delivered to the several bins by the spouts 18. The particular bin to which the grain must be delivered is determined by closing er opening the required number of slides 18a. lhen it is desired to unload the bins, it is only necessary to raise the slides 32, and the grain will fall out onto the lower conveyer belts 19, from whence it is delivered to the chute 23 and thence to the boot, from which it may be transferred to the wagon or other conveyance for the purpose of carrying it to any point desired.

I do not desire to limit myself to the precise form and construction of elevator building shown, as it is obvious that many minor changes maybe made in the Ventilating features and other parts of the building without departing from the scope of my invention.

Having thus described my invention, what 1 claim is: l

1. An elevator building having a series of bins, a perforate Ventilating frame in the outer wall of each of said bins, each bin also having a perforate Ventilating opening` in the fioor thereof and a slide in one of the walls through which the grain is passed, a hood offset from the wall and extending horizontally the length of a series of bins and covering the outer perforate Ventilating openings of said bins, substantially as described.

2. An elevator building provided with bins having a perforate Ventilating opening in the outer wall of each bin, perforate Ventilating openings in the bottom of said bins, the meshes of said perforate openings being of such a size as to prevent the escape of large grain, doors adapted to cover said openings in the outer wall and bottom of each bin, whereby the bin is adapted to receive small grain, substantially as described.

3. An elevator building having a series of bins, the outer vertical wall of said bins having a perforate Ventilating opening therein, an imperforate,water-shedding hood offset the Wings, bins in said Wings, a separate Ventilating frame in the Wall of each bin and fixed exterior Watershedding hoods separated from and covering said frames, Sub- 15 stantially as described.

In testimony whereof I have affixed my i signature, in presence of two Witnesses. JAMES C. TOBIAS.
